Join our first meetup on 24 June 2026. **Program:** 17:00 – 18:00 Walk-in + Dinner 18:00 – 18:45 Zero Trust: Applying Military Procedures to Cybersecurity Challenges - by Laurens Blankers (JDriven) 18:45 – 18:55 Break 18:55 – 19:40 Let's use Spring Boot to build games, because why not? - by Alexander Chatzizacharias (JDriven) 19:40 – 20:00 Practical AI Developer Setup Demo (by Alexander Chatzizacharias) — Learn how to integrate AI tools into your daily development workflow + Giveaway: **Win a 1-month Claude Code MAX subscription (worth €100)** 20:00 – 21:00 Networking Drinks About the talks: **Let's use Spring Boot to build games, because why not?** **Alexander Chatzizacharias - JDriven** If you work on enterprise grade microservices on the JVM, you have undoubtedly heard of Spring Boot. Most developers see it as the reliable backbone of enterprise software. It is stable, predictable, and safe. But what if we took all those conventions and threw them out the window? What if we repurposed the IoC container, event listeners, and bean lifecycles to reveal what Spring Boot was always meant to be? A game development framework! Join Alexander as he attempts to deconstruct and demystify the Spring ecosystem by forcing it to do things it was definitely not designed for. We are not talking about simple text adventures here. We are talking about building complex, real-time games like a Terraria clone or a souls-like RPG, all powered by the same annotations you use for your day job. This session explores what happens when you learn technologies by breaking them. Whether you are a Spring veteran or a newcomer, this talk offers a fresh perspective on the tools you use every day. You will leave with a better understanding of how Spring Boot works under the hood and the inspiration to build something completely unnecessary, just because you can. Come for the absurdity, stay for the laughs, and see what happens when you strip away conventions and best practices in the pursuit of a wild idea. **Zero Trust: Applying Military Procedures to Cybersecurity Challenges** **Laurens Blankers - JDriven** Cybersecurity is becoming more and more challenging. A lot of ‘new’ solutions are being proposed, including Zero Trust. Although, if you really drill down to the core, Zero Trust proposes a way of working which has been standard in military organisations around the world for over 80 years. Join me in breaking down Zero Trust into a number of easily understood principles including a number of approaches which can be applied to your software today. Laurens is a Java Software Engineer with over 20 years of experience. He excels at extracting the bigger picture and applying this to the smallest details. He combines this theoretical knowledge with his vast practical experience and hands-on mentality. Laurens has significant experience with a number of Java based platforms, including Jakarta EE and Spring (Boot). Ranging from REST microservices in the cloud to applications for controlling custom hardware on the desktop. In his personal life Laurens enjoys Science Fiction, board games, and history of technology. **Practical AI Developer Setup Demo** **Alexander Chatzizacharias - JDriven** After the talks, Alexander will give a live demonstration of his AI-powered development setup and workflow. Discover how modern AI tools can help you write code faster, improve productivity, automate repetitive tasks, and accelerate learning. You'll get a practical look at the tools, techniques, and workflows that developers are using today to get the most out of AI. At the end of the demo, we'll hold a giveaway where one attendee will **win a** **1-month Claude Code MAX subscription (worth €100)**.

*(🇬🇧 English below)* Voordat een bordspel of kaartspel kan worden uitgegeven, moet er veel aan het spel getest worden om zeker te zijn dat het leuk is, duidelijk is en altijd goed werkt. Daarom komen we **elke 2 weken** met spelauteurs uit de regio samen om prototypes van spellen te testen en ze zo beter te maken en misschien ooit wel gepubliceerd te krijgen. Om 8 uur verzamelen we bij [StartUp Nijmegen](https://startupnijmegen.nl/) voor een speltestavond. Afhankelijk van het aantal aanwezigen en prototypes dat er wordt meegenomen (neem zelf ook iets mee als je wilt) vormen we een aantal groepen. Bij kleinere spellen kun je in de loop van de avond van groep wisselen, bij grotere spellen moet je dat even overleggen. **Ook als je zelf** **geen spellen maakt** of een spel hebt dat je wilt testen, ben je natuurlijk van harte welkom. Het is voor ontwerpers heel fijn om de mening van zo veel mogelijk andere mensen te krijgen. En heel eerlijk: het testen van nieuwe spellen is ook gewoon heel leuk! We gaan door tot een uur of 11, maar voel je vrij al eerder naar huis te gaan. Er is **gratis koffie** **en thee** bij StartUp Nijmegen. Voor fris, bier of wijn wordt een kleine bijdrage gevraagd. StartUp Nijmegen ligt tegenover het station. De auto kun je parkeren in de naastgelegen Keizer Karelparkeergarage (50 cent per uur). Er is hier ook een afgesloten fietsenstalling. De testavonden in Nijmegen zijn elke **2e dinsdag** en elke **4e woensdag** van de maand. Zet die dus vast in je agenda (tip: zet met [deze iCal link](https://calendar.google.com/calendar/ical/c_d2267afce516f9296468270649b3f44da6c06cbc0bc3de05f049992373db5f4f%40group.calendar.google.com/public/basic.ics) ze automatisch in je agenda)!

Je vindt ons daarnaast ook in het #Nijmegen kanaal op de [Discord-server van het Spellenmaakgilde](https://discord.gg/6JzD6Sz2m5). 🇬🇧 **For English-speaking guests:** Before a board game or card game can be published, it must undergo extensive testing to ensure that it is enjoyable, clear, and always functions properly. Therefore, **every 2 weeks**, we gather with game authors from the region to test prototypes of games, thereby improving them and, perhaps, getting them published someday. At 8 PM, we gather at [StartUp Nijmegen](https://startupnijmegen.nl/) for a game testing evening. Depending on the number of attendees and prototypes brought (feel free to bring something yourself), we form several groups. For smaller games, you can switch groups throughout the evening, but for larger games, you should discuss this. **Even if you** **do not design games** or have a game you want to test, you are, of course, very welcome. It is very beneficial for designers to receive feedback from as many people as possible. And to be honest: testing new games is just a lot of fun! We continue until about 11 PM, but feel free to go home earlier if you wish. There is **free coffee** **and tea** at StartUp Nijmegen. You can park your car in the adjacent Keizer Karel parking garage (50 cents per hour). There is also a secure bicycle parking facility here. The testing evenings in Nijmegen are every **2nd Tuesday** and **4th Wednesday** of the month. So be sure to mark those in your calendar (tip: automatically add them to your calendar with [this iCal link](https://calendar.google.com/calendar/ical/c_d2267afce516f9296468270649b3f44da6c06cbc0bc3de05f049992373db5f4f@group.calendar.google.com/public/basic.ics))!

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
